Triglycerides Vegetable oils

Fatty Acid Esters and Fatty Alcohols Fatty acid esters are obtained by transesterification of triglycerides (vegetable oils) or by esterification of fatty acid with alcohol or polyols. Fatty alcohols are obtained by hydrogenation of esters on metal catalysts. Fatty acid esters and fatty alcohols are useful platform molecules to prepare surfactants, emulsifier, lubricants and polymers.

Castor oil is also known as riciaus oil, oil of Palma Christi, tangantangan oil, and neoloid. Typical of vegetable oils and most fats, castor oil is a triglyceride of various fatty acids (see Fats and fatty acids.) Its uniqueness stems from the very high (87—90 wt %) content of riciaoleic acid, stmcturaHy... 

An experiment describing the analysis of the triglyceride composition of several vegetable oils is described in the May 1988 issue of the Journal of Chemical Education (pp. 464-466). 

Conversion yields in the bienzymatic system have been optimized by using pure substrates (triglycerides) as well as crude vegetable oils (Table 4) rich in a range of polyunsaturated fatty acids (sunflower oil or linseed oil). The use of crude reactants approaches a more realistic scenario for the industrial-scale manufacture of hydropexides. 

A continuous stirred tank reactor has been reported for the hydrolysis of the triglycerides existing in vegetable oil in the presence of the aqueous phase and for synthesis reactions (Table 5). A microfilter can be used to prevent the immobilized enzyme from leaving the reactor. Kawano et al. [115] investigated the hydrolysis of olive oil in octane with Candida cylindracea lipase in aqueous solution in a Vibro Mixer reactor containing vibration plates connected to the crankshaft of a motor and oscillated with fixed rates. 

Biodiesel is a fuel derived from renewable natural resources such as soybean and rapeseed and consists of alkyl esters derived from transesterification of triglycerides with methanol. In spite of all the advantages of biodiesel, such as low emissiotts, biodegradability, non-toxicity, and lubricity, the major hurdle in penetration of biodiesel is its high cost because of the expensive food grade refined vegetable oil feedstock. 

Water-immiscible, volatile, or more likely nonvolatile liquids such as vegetable oils, aromatic and aliphatic hydrocarbons (mineral oil), medium-chain triglycerides, and acetylated glycerides. 

Alcohols are also widely produced from fats and oils, and in some cases one of the oldest techniques utilised in the manufacture of soap, fat splitting, is also used as part of the process. Vegetable oils as well as animal fats are all triglycerides and consequently a key step of the various technologies used in the alcohol manufacture involves the separation of glycerine. Oleochemical alcohols are produced using two... 

Vegetable oils or triglycerides obtained from the seeds of various plants are the source of a wide variety of fatty acid esters and derivatives (fatty acids and alcohols) with different molecular structure (chain length, number and position of...

Conversion of triglycerides, found in animal fats or vegetable oils, to corresponding alcohols which contain less than 1% branching.
